Declarative Specification Based Override Mechanism for Customizing Data Centers Deployed on Cloud Platforms

4. The computer-implemented method of claim 2, wherein the filtering criterion specifies a set of values for an attribute from the one or more attributes associated with a data center entity from the one or more data center entities such that the data center entity matches the filtering criterion if the attribute associated with the data center entity has a value within the set of values.

5. The computer-implemented method of claim 2, wherein the filtering criterion comprises an expression based on the one or more attributes associated with a data center entity from the one or more data center entities.

10. The computer-implemented method of claim 1, wherein the declarative specification comprises definitions of the one or more data center entities, wherein a data center entity from the one or more data center entities includes one or more service groups, wherein a service group from the one or more service groups comprises a set of services.

11. The computer-implemented method of claim 10, wherein a service group from the one or more service groups further specifies a set of clusters of computing nodes, wherein one or more services are associated with a cluster of computing nodes from the set of clusters of computing nodes, wherein the data center deployed on the cloud platform includes the cluster of computing nodes and executes the one or more services on the cluster of computing nodes as specified in the declarative specification.

16. The non-transitory computer readable storage medium of claim 12, wherein the declarative specification comprises definitions of one or more data center entities, wherein a data center entity from the one or more data center entities includes one or more service groups, wherein a service group from the one or more service groups comprises a set of services.
